Justification:
The Giant Sable has a very restricted range in Angola and has suffered from the effects of many years of military conflict in its area of distribution. In all areas surveyed, the estimated decline is estimated at 85-90% over 25 years, representing 3 generations (8-9 years), based on decline in area of occupancy, habitat quality and actual levels of exploitation. Total numbers surviving are estimated (2007) at 200-400 individuals, and no known subpopulation currently contains more than 50 mature individuals. It is possible that further research will show that populations >50 mature individuals exist in at least one site (Luando Strict Reserve), but until this has been unequivocally demonstrated the precautionary principle is applied. Although the situation in Angola has stabilized to some extent, populations are still declining and Giant Sable face several threats, including recent occurrences of hybridization with Roan Antelope (Hippotragus equinus).
